sTovE-DRUM.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that'we, W. P. HEBBURN andWILLIAM REINER, of Clariuda, in the county of Page, and State of Iowa, have invented a new and improved Stove; and we do hereby declare that the following is-a full, clear, and exact description` thereof, reference being had to the accompanying drawings, making a part of this specification, in whichp Figure 1 is a perspective view of a Wood-burning stove, inV red lines, showing the air-heating pipe ar- Figure 2 is a vertical section 'taken centrally'through awood-burning stove, showing the air-heating pipe arranged in it.

SimilarA letters of reference indicate correspond-ing parts in the two figures.

The object yof this invention is to increase the heating-capacity of a stove of any given size, by so arrangl ing an air-conduit, which is open at. both ends to the external air, within the fire-chamber of a direct-draught stove, that such conduit shall interrupt the direct passage of the heated products of vcombustion on their way to theescape-pipe, and at the same time interrupt the passage of the air through it, thereby adapting the stove to serve as a radiator of heat, as well as a means for'warming rooms by air," which is heated in its passage through the said conduit, a's will be hereinafter explained.

To enable others skilled in the art to understand our invention, we will describe its construction and operation.

In the accompanying drawings, we have represented our invention, applied withinthe fire-chamber of a direet-draught sheet-iron stovev A being the body of such a stove, which may be made of cylindrical, elliptical, rectangular, or of any other suitable shape, and which is provided near its base 'with a door, D, to which a register may be ap plied for regulating the introduction of air in the tirechamber for supplying` combustion.

Near the upper end of this stove is a pipe, G, for allowing the products of combustion to escape iuto'the chimney.

Within this stove we have arranged a pipe of airconduit, B B', which may be made of any suitable diameter, and which conducts cool air from the room at the base or-bottom of the stove, heats thel air, and dis' charges it iom Ythe top of the stove; as indicated by the course of the arrows in iig. 2. The peculiarity of our stove consists in the arrangement of the sections B B', of the air-heating conduit between the escapepipe G, for the products of combustion, and the irebed, so as to leave between such sections, narrow spaces through which the heated products are allowed to rise slowly on their way to the pipe O. The sections B may be arranged in horizontal planes, or they may he more or less inclined, and they are so arranged as to be exposed to the direct action ofthe ame, and heated products, so that in circulating beneath, between, and above the pipes, the air passing through them will absorb and carry o a very large amount of heat whichv would, without such arrangement, be carried off into the chimney.

The said horizontal sections B' are connected at their ends by angles or elbows a a, aud they communicate with the external air at the base and top of the stove, by means of vertical sections of pipe B B, as clearly shown in gs. 1 and 2 ofthe drawings.

The elbows may be made of cast-iron, united to sheet-iron sections, or if desirable, all the sections composing the conduit may be made of cast-iron. These elbows or angles will retard the passage ofi air through the several sections, by deiectiug the currents from a straight eourse,'and by these interruptions the air Will be retained within the bodykof the stove long enough to' become thoroughly heated before it is allowed to escape from the last section B at the top of the stove.

We do not confine ourselves to the arrangement of the sections of pipe collectively in a horizontal plane, as they may be otherwise arranged, and if desirable, two or more tiers of pipes may be so arranged between the bed of the fire and the escape-pipe C, as to be exposed to, and retard the products of combustion on their way to said pipe.

We-are aware that Hue-stoves and other forms of stoves have been provided with air-heating chambers, and pipes, arranged in a variety of ways within, and exterior to the fire-chamber of the stoves, but we .are not aware, that previous t'o the date of our invention, there has ever been constructed or invented, a stove having an air-heating conduit composed of sections of pipes arranged so as to interrupt the escape of the products of combustion, by contracting the upper portion of the fire-chamber below the escape-pipe, which sections are also so constructed as to interrupt the passage of air through them long enough for it to become considerably heated.

What we claim as new, and desire to secure by Let- -ters Patent, is-

A stove having arranged within its {ire-chamber, and betweenfthe fire-bed and the escape-pipe for the products of combustion, a number of hollow angular sec`- tions B', united to vertical sectionsB B, and adapted to operate substantially as described.
